  • Efficient One-to-One Coupling of Easily Available 1,3-Dienes with Carbon Dioxide
    作者:Jun Takaya、Kota Sasano、Nobuharu Iwasawa
    DOI:10.1021/ol2002094
    日期:2011.4.1
    reaction of atmospheric pressure carbon dioxide with 1,3-dienes is realized for the first time through PSiP-pincer type palladium-catalyzed hydrocarboxylation. The reaction is applicable to various 1,3-dienes including easily available chemical feedstock such as 1,3-butadiene and isoprene. This protocol affords a highly useful method for the synthesis of β,γ-unsaturated carboxylic acid derivatives from
